VEHICLE-WHEEL RIM.

Specification of Letters Patent.

Patented April 28, 1908.

Application filed. February 20, 1907. Serial No. 358,463.

To all whom it may concern:

Be it known that I, EDWIN COUPLAND SHAW, a citizen of the United States, residing in the city of Akron, county of Summit and State of Ohio, have invented certain new and useful Improvements in Vehicleheel Rims, of which the following is a specification, reference being hadto the accompanying drawing s, which form a part thereof.

My invention relates to that class of vehicle wheel rims adapted for use'with tires of resilient materials, and more particularly to rims adapted for use with detachable tires.

I have described and claimed in a companion application an improved vehicle wheel rim having one tire flange mounted upon the rim proper or channel-iron, an opposing tire flange mounted upon a removable transversely split ring, and means for securing locking engagement between the split ring and the channeliron.

The object of the invention described and claimed in the present application is to provide a useful modification of the means for securinglocking engagement between the channel-iron and the split ring upon which the removable tire flange is carried. I ac complish this object by means of a retaining flange upon the channehiron, two downwardly extending lugsupon the split ring,

near its terminals, two. slots in the channel-- iron adapted to receive said lugs, and a screw or key adapted. to pass through an upwardly projecting lug upon the channel-iron and through mutually registering grooves extending laterally through the contacting surfaces of the split ring terminals.

In the drawings Figure 1 is a perspective view showing a section of the tire and my improved means for attaching the tire to the wheel. Fig. 2 is a cross-section of the tire and rim upon the broken line of as as Fig. 3 showing the means for securing locking engagement between the channel-iron and the flange-bearing ring. Fig. 3 is a side view of the tire and rim, 2. part being broken away to show details of construction of the locking means.

I have shown In device as applied to a tire and rim of the c enchertype, in which the flanges are curved upwardly and inwardly to grasp and hold beads formed upon the tire casing, but it will be obvious to those skilled in the art that by altering the shape of the tire flanges my device can be adapted for use with tires of any form. Y

Referring to the drawings: In Fig. l, 1 is the wheel felly, the channel-iron 2 being adapted to be aflixed thereto. Formed upon or permanently secured to this rim is the flange 3, adapted to engage one edge of the tire; At its other edge the rim or channel iron is extended laterally and the portion beyond the wheel telly preferably has a slight downward tendency toward the hub of the wheel. This edge terminates in an upturned retaining flange 4. extending the entire length of the rim, forming a seat for the removable ring 5 and securing it against laterally outward displacement. The form of this portion of the channel-iron may of course be varied; for example, it may have a downward offset instead of the inclination, but the essential feature is that the upper edge of the retaining flange must be on a level with or below the surface of the main portion of the rim, so that a tire can be slipped over it without stretching, The form of the retaining flange is likewise immaterial, except that the flange or its equivalent must form a seat for the removable ring, adapted to secure it from laterally outward movement' The removable ring 5 comprises a base portion and a second tire flange. The base portion has its undersurface formed to seat upon the extension of the rim in such a manner that when the ring is seated the tire flange is in position to engage the edge of the tire. This ring is continuous except at a single point where it is transversely split to allow it to be attached or removed at will. Upon the under-side of this ring, and near its terminals, are provided two lugs 6 and 7, the posterior edges of which are preferably beveled. In the portion of the channel-iron which carries the removable ring and at any convenient point upon its periphery are cut slots shaped to' receive these lugs and so located that when the lugs are inserted therein the ring terminals contact in longitudinal alinement. The lugs may be placed at the ends of the ring terminals so that their anterior faces are.

flush with the ring ends. In this case a single slot is suflicient. The structure is stronger, however, if the lugs are separate and two slots are provided. Upon the retaining flange 4, at a point opposite to the joint of the split ring, when the latter is in position, is provided an u wardly extending lip or lugS which is pe orated to admit a screw or key 9. In the contacting surfaces of the ring terminals and registering with the perforation in the lip 8 are provided mutually registering grooves and the center of the holethus formed is in the plane of the contacting surfaces. I A bolt or key-pin 9 is provided, adapted to pass through these two oles and to secure the ring terminals to the lip 8.

The operation of my device is as followsr To attach a tire the split ring is removed, the

tire applied to the rim and made to engage flange 4 prevents laterally outward displacement of the split ring, the lugs 6 and 7 which are inserted in the slots prevent any creeping? or movement of the ring about the rim, and the screw 9 secures the ring terminals to the channel-iron and locks the lugs in the slots. To remove the tire this operation -is reversed: The screw 9 is removed, whereupon the lugs can be removed from the slots and the split ring and the tire detached. If desired both tire flanges may be made detachable by duplicating the split ring and the attaching means but in practice this is usually found unnecessary and undesirable. Again the split ring may be constructed. in two or more sections by providing similar locking means at the terminals ofthe several sections and with large and heavy structures this may be found advantageous. The split ring should bev formed to fit ac curately within its seat and to the channel iron, 'and in. consequence it may be found difficult to draw togetherthe split ring ter' minals and to insert the lugs within the slots.

-To facilitate this operation I provide a jointed lever 10, as shown in Fig. 1. A in 11 in one arm is inserted in a hole 1'2 drilled in one of the ring terminals, near its extremity, and a pin 13 upon the other arm of the lever is inserted in a hole 14 drilled in the other ring terminal, near its extremity.

Thereupon, by means of the, lever, the ring terminals can be drawn together, the lugs inserted in the slots and thescrew adjusted. Having described my invention what I :laim is:
